Which Groupset?

Tacx do some ceramic ones which look good. I'm thinking of replacing my 105 ones with them.

I have a set of Ultegra for RD6700 which you could have. But would probably wreck your bike.

105 one is cheaper.

does anyone know the cheapest place to get a super record mechanical groupset? I am treating myself (on 0% finance)(don't judge). I haven't found anywhere cheaper than comtat yet.

So disc groupsets...

Talk to me.

I am looking for a disc groupset for my new 'nice' bike. Essentially it's going to be my only road bike, and probably my only major bike purchase for a long time.

That said money is a definite consideration at the moment so I don't want to needlessly spunk money. Especially as I'll need new wheels too.

First decision is cable or di2. If I go di2 then I guess theres only one answer; 6870 Ultegra + R785 shifters, right?

9070 seems to be £1,500 + R785 shifters + RD mod to long cage sounds like £££s for not much gain.

Then it's cable vs hyrdo. I'm pretty much sold on hydro if I'm going to disc. In which case its R685 shifters plus whatever group I want from DA to Tiagra(?). If I go cable then it's 105, right?

Is that a pretty good summation, or is there any thing I'm missing?

Any hints and tips appreciated. Cheers.

Does it have to be hydraulic?

Etap + spyres?

I'd definitely go hydro, even Spyres are a poor imitation. I've been running hydros with cables, mainly because I race cyclocross on that bike and the cost of a Di2 replacement rear derailleur is too much to consider it a disposable item, and the brakes are absolutely faultless.

685 shifters and ultegra or 105 mechs and stuff

Ultegra Di2 + hydro and if you've got flat mount then you want RS805 not R785 I think.

Didn't seem much point to DA for my new bike. Needless expense.

Any thoughts on apex 1x? Never used sram, just shimano, so not sure what to expect?

Etap + spyres?

Unfortunately it meant to be a bike for life™. #theoldjokes etc.

@andyp - cheers. So I'm now 100% sold on hydro.

It's just the di2 vs cables to decide. I should probably do a price comparison to see what the actual extra cost is. The plus with cables is I've set them up before and they are a known. However, di2 is a bit more bling.

@hippy - good point, I don't actually know what type of mounts the frame has.

I've had a bit of a look at 2nd hand stuff, but there doesn't seem to be a huge amount in it at the moment. Lots of external batteries, which reduces the savings once you budget internal batteries.

Incidentally if anyone has a setup they're looking to shift let me know.

It's too new for used stuff to be being sold off. Only older series DA is really out there.

I need some di2 tt shifter pods - where's cheapest place?

Hint:

Chips

What chainset is this? New DA?

Maybe a Q for @edscoble or those who work on a lot of bikes:
What Shimano/SRAM 10sp cassettes have most/all of the sprockets on a carrier, as opposed to loose? My current only has the last 2-3 sprockets and has chewed up the soft alloy freehub body.

The Shimano tech diagrams should show you. I used Ultegra when building custom cassette because DA had 2-3-1-1-1-1-1-1 whereas Ultegra has 3-2-1-1-1-1-1-1

Or get a steel freehub body or just file the little bits of squished metal off when you swap cassettes.

You want the Tiagra 4600, where the 7 biggest are joined.

Great, thanks Hippo

No! They're not on a carrier and can dig in as well.

Ultegra is what you need, and put some grease on the freehubs body.
